An efficient mapping scheme for Locator/ID Separation protocol

Internet has transformed from few nodes of ARPANET to the billions of nodes worldwide. The current Internet routing architecture suffers from scalability and performance problems with the increase in number of users day by day. Internet core i.e. Default Free Zone (DFZ) in Internet, is being polluted due to increase in size of BGP routing table. Bigger routing table causes more delay in the packet forwarding process. Locator/ID Separation protocol is the most feasible solution considered for cure of this problem which separates the identity of the host and its location so that only the location of host is advertised in the global routing table keeping the scope of identity local to the enterprise. However, this requires the existence of a mapping scheme for lookup from identity to location. We have proposed a mapping scheme which works efficiently in providing the lookup mechanism without any modification to the existing protocol stack. The architecture is well suited in minimizing the lookup delay and protocol overhead on Internet.
